Title: Linear controller for synchronous motor
Inventor: TAKIGUCHI JUNICHI
IPC: H02P23/14
Filed: 1988-01-21
Abstract: PURPOSE:To conduct linear control having high accuracy even when there are fluctuations in the system parameter of a synchronous motor by estimating interference voltage with an interference voltage estimator and feeding back the interference voltage. CONSTITUTION:An interference voltage computing circuit 5 computes an interference voltage arithmetic value 11 from a current signal 13 flowing through a synchronous motor 4 and a rotational angular velocity signal 8 of the synchronous motor 4. Interference voltage generated in the synchronous motor 4 is offset by the interference voltage arithmetic value 11, and the dynamics of the synchronous motor 4 are linearized. An interference voltage estimator 6 estimates interference voltage 10 from a torque command signal 15 and a current signal 13. A torque input signal 12 is produced from the interference voltage 10, a current error signal 9 and the interference-voltage arithmetic value 11, thus dynamically offsetting interference voltage.

Each filter 110 is provided with the diffracting grating 120, and the period of the diffraction grating 120 is slightly different among filters 110. The effective refractive index of a light guide layer 130 is changed by the electric signal supplied from a power source 140 to control the effective period of the diffraction grating 120. When the effective period of the diffraction grating 120 is changed, the transmission stop wavelength range of the filter 110 is changed. Thus, transmission stop wavelength ranges of plural filters 110 coupled in series are simultaneously controlled by a controller 100 and arbitrary one of plural signal light beams different in wavelength is selected and is stably transmitted through.

IPC: G05B19/05
Filed: 1990-01-24
Abstract: PURPOSE:To prevent wasteful latency time occurring by holding a sequence instruction for readout variably conforming to the time of analytic processing. CONSTITUTION:An instruction decoder 16 analyzes a read out instruction whether it is an application instruction or a bit instruction. When it is the application instruction, a NAND circuit 13-1 is opened with the output of the decoder, and the output of an instruction fetch pulse generator 12 is inputted to the D terminal of a D-FF 8. since both output of the D-FF 8 and the NAND gate 13-1 are '1' when the NAND gate 13-1 is closed, a readout signal that is the output of an AND gate 15-2 is held only for a time equivalent to one clock. Since the output of the D-FF 8 goes to '0' only for a time equivalent to one clock when the NAND gate 13-1 is opened, the output of the AND gate 15-1 also goes to '0' for that time, and a readout signal 2 can be held only for a time equivalent to two clocks.

Filed: 1980-02-05
Abstract: PURPOSE:To prevent the mixing ratio of toner from becoming abnormal at abnormal humidity by stopping the supply of the toner when the humidity is not within a prescribed range and by supplying a constant amount of toner for every copying operation. CONSTITUTION:When the output voltage value of humidity sensor 19 is lower than reference voltage Vb, the output side of comparator 21 is held at a low level and the output side of NAND circuit NAND is changed from a high level to the low level via INV2 to supply the output to AND1 as an input, so that AND1 will close the gate. When the output voltage value of humidity sensor 19 is lower than reference voltage value Vb, toner supply control operation performed corresponding to the detection result of sensor 5 for the amount of sticking toner is invalidated. On the other hand, while the output voltage of humidity sensor 19 is lower than reference voltage Vb, a constant amount of toner is supplied to continue copying operation.

IPC: G06F9/48
Filed: 1991-01-09
Abstract: PURPOSE:To reduce the priority discrimination timing frequency and to attain a fast response time by scanning 2<n> priority levels in the (n) timing frequency and detecting an interruption request signal having the highest priority. CONSTITUTION:The 2<n> priority levels are set to an interruption signal, and the priority bits 116 and 117 of all interruption signals produced in the (n) timing frequency are compared successively with the storage contents of a busy mode priority register from the highest significant bit through the least significant bit. Thus the interruption signals corresponding to both bits 116 and 117 having the values of their contents more preferential than the other bit contents are detected as the interruption request signals of the highest priority through the comparison of a series of bits. Based on these interruption signals, an interruption processing request signal is outputted to a central processing unit.

P1 shows the position of R1 when an ultrasonic signal reaches the receiving terminal R1 from the transmitting terminal S1 through a time t1 and P2 shows the position of R2 when the signal of the transmitting terminal S2 reaches the receiving terminal R2 through a time t2. When the advance speed of the vehicle Q is set to Va and the propagation speed of an ultrasonic wave in the vehicle Q is set to V(T), the relation of Va=(t2-t1)L/2t1t2 is formed and the times t1, t2 are measured to calculate Va by CPU. By this method, Va is obtained regardless of temp. and miniaturization, cost reduction and the enhancement of reliability can be achieved.
